哈尔乌素露天煤矿5台卡特24H型平地机,常在复杂工况中作业。这5台平地机工作装置操纵阀在使用1000h左右,均会出现旋转轴密封处漏油现象。更换操纵阀成本高,且维修麻烦,为此我们决定对该阀进行改进。1.操纵阀工作及润滑原理卡特24H型平地机工作装置操纵阀分为2组,其中司机左侧操纵阀由4个单体阀组成,司机右侧操纵阀由5个单体阀组成。每个单体阀由1个操控杆进行操纵,
Haer Wusu open-pit mine 5 Carter 24H-type grader, often in complex conditions in operation. This 5 grader working device control valve in the use of 1000h or so, there will be leakage of oil seal rotating shaft. Replacement of the control valve is costly and troublesome to repair, for which reason we decided to make improvements to the valve. 1. Control valve work and lubrication principle Carter 24H-type grader machine control valve is divided into two groups, in which the driver left control valve by the four single-valve, the driver’s right control valve by the five monomer valve. Each single valve by a lever to manipulate,
